“…Forster (2009) describes even higher price differentials for chickens between other provinces and for ducks. Van Kerkhove et al (2009) andObi et al (2009) also reported price differentials as key drivers of illegal movement of poultry into Cambodia and Nigeria.…”

“…Most research on HPAI H5N1 transmission and outbreaks has been associated with commercial poultry production and legal movement between formal markets (Van Kerkhove et al 2009;SanchezVizcaıno et al 2010;Biswas et al 2011;Desvaux et al 2011;Fourniéa et al 2013).…”

“…This illegal movement poses a high risk of HPAI H5N1 transmission due to the high poultry numbers being transported and housed together, and the lack of biosecurity measures (Rappole and Hubálek 2006;Van Kerkhove et al 2009;Wang et al 2010). While the drivers of illegal movement of poultry are mostly economic, they can also be social and cultural.…”

“…Live chickens, ducks and turkeys are often exchanged between owners for breeding, fattening, showing or consumption (Ramdas 2009;Alders et al 2014). In many countries, poultry are used for ceremonial or religious purposes with high-demand periods during festival and wedding events (Aklilu et al 2007;Van Kerkhove et al 2009;Wiratsudakul et al 2014 HPAI H5N1 has been prevalent in Indonesia since 2003, resulting in 195 cases of human infection of which 165 have been fatal mostly in Java but also on the islands of Sumatra, Sulawesi, Bali and Lombok (WHO 2014). Poultry outbreaks have occurred in all but one of the 34 provinces in Indonesia, and these have had significant social and economic impacts to poultry producers and the industry (Hartono 2004;Rushton et al 2005;Basuno et al 2010;Alders et al 2014).…”

Informal movement of domesticated poultry and wild birds is considered a major threat in terms of highly pathogenic avian influenza (HPAI) H5N1 transmission between birds and from birds to humans. However, the risk of transmission from informal illegal poultry movement has received little attention in Indonesia where human fatalities are the highest in the world. This research investigated the illegal movement of adult poultry between the islands of Java, Bali and Lombok to determine the potential risk of HPAI H5N1 transmission. The aim was to determine known origins and destinations of poultry, estimated quantity and types of birds, people involved and the drivers of illegal movement. Transportation and handling methods and views on how to minimise illegal movement were also investigated. In-depth interviews were carried out with 71 key informants in Bali and Lombok in 2009. East Java was the main origin of poultry entering Bali, followed by Central Java and Lombok. Interviewees estimated that over 10,000 village chickens, 500 ducks and 50 fighting cocks were brought into Bali per month from all origins. However, there were significant discrepancies with quarantine records indicating that the majority of birds imported illegally are not detected. We conclude that although informal illegal movement of poultry in Indonesia poses a potentially high risk for potential HPAI H5N1 transmission if birds are infected, much can be done to increase surveillance, encourage reporting of sick birds, educate traders about the risks and provide effective quarantine within an appropriate cultural framework.

“…The role of live bird markets (LBM) in the epidemiology of AI was revealed in the 1997 Hong Kong epidemic (Sims et al 2003;Kung et al 2007). Since then several researchers have reported that H5N1 viruses circulated among geese, ducks and chickens in LBMs in affected Asian countries since 2003 (Nguyen et al 2005;Webster et al 2006;Jadhao et al 2009;Liao et al 2009;Van Kerkhove et al 2009;Indriani et al 2010;Wan et al 2011;Sarkar et al 2012). Additionally, many festivals associated with raising (either commercially or domestically) ), selling and transporting the poultry birds also plays a role in spreading of the virus in Africa (Musa et al 2009) and Thailand (Ortiz et al 2007;Hinjoy et al 2008;Tiensin et al 2009;Santhia et al 2009).…”
